I picked up my new Canon 1DX Mark III a couple weeks ago, and actually have not had too much time to get out shooting with it just yet. But the small amount of time I have spent with it, I do have a few first impressions of it that I thought I would share until I have more time to spend with it.  The following are a few of those first impressions, and what I still plan to come when it comes to testing and shooting the 1DX Mark III.


AF Points

The marketing materials had me really excited, it stated that the 1DX Mark III was coming equipped with 191 AF Points (155 cross-type points) with all of them being f/8. My thoughts were “Finally, more coverage of the frame”, making it a little easier to frame shots when you want the subject further down in either the left, or right, corner, when trying to capture an animal with a landscape behind it.  Well I got excited for nothing, while there are more than 130 more AF points, they are covering not much more of the frame (maybe no more of the frame).


What that means is that there are a ton of really tiny AF points that can help increase the precision of your autofocus, assuming it falls within the array of points available (and not out in no mans land where there are no AF Points).  With the AF points being so small, it makes me wonder if there is really any use not for the Spot AF point, because it is just such a tiny little focusing point.  I guess I will get an answer to this once I get more time with the camera, and test the Autofocus a little more carefully.


There has also been a revision to the “Cases” where you can set the parameters for the responsiveness of the autofocus.  The changes that I have noted (but not had a chance to test yet) are that there are now only 4 cases (as opposed to 6).  Canon has added an auto case which is supposed to adapt to how the subject moves.  And finally they have removed the parameter for AF Point Auto Switch, which I am not that bothered by, because I didn’t find that it was overly useful anyway.


Auto ISO

There were no notable changes with the Auto ISO, more specifically, Canon is still only offering full stops for shutter speeds when setting the Auto ISO, which definitely does bum me out a little bit, because having 1/3 stops would be way more useable.


New Button

The new AF On button with smart controller allows you to scroll the autofocus point without the need to press another button first.  It’s a pretty slick button, however I do find that it is pretty sensitive, so I think it will take some getting used to in order to work with it quickly.  I also wonder how it will respond when shooting in the rain, and if my fingers are wet.  With the amount of time that I spend on the coast of British Columbia, I am guessing I will get to put it to the test.


Other Notes

I have noticed in the little bit of time that I have spent with the camera, it seems to be a bit quieter especially when shooting large bursts, it sounds like the mirror is less “slappy”.  Coupled with this is that the mirror blackout does not seem to be as long as it is with the predecessor the 1DX Mark II.


What’s Next?

Next on the agenda for me is to spend some more time actually shooting the camera.  In addition, I hope to spend more time testing the ISO performance, and comparing it to the 1DX Mark II, and also testing the Autofocus and how it compares to the 1DX Mark II.


If you have any questions about my thoughts on the 1DX Mark III, feel free to contact me at

Today is a big day for this Canon user.


My Canon 1DX Mark III has arrived.  I am so excited to get out and try it, and compare it to the 1DX Mark II.  Ergonomically it feels pretty similar to the 1DX Mark II, but we will see how it stacks up compared to the 1DX Mark II, especially for my focus, wildlife photography.


Also, last night Canon has released a statement that it is working on a new mirrorless, the EOS R5.  I am very much looking forward to trying a new mirrorless camera.  I feel like the EOS R really didn’t meet my needs, especially as an owner of the 5D Mark IV, so I am looking forward to Canon’s next attempt at the mirrorless cameras, and hopefully this fills a void in my current camera line up.


The EOS R5 is advertised as having 20 frames per second, and 8K video, but the rest of the details are pretty vague.  Based on the photos that are floating around online, the camera looks much more ergonomic, and more similar to the 5D Mark IV.   There are lots of rumors out there, so I guess we will just need to wait and see what the actual specs are when the “real announcement” is made.  Canon also mentioned that they are working on a 200-500, and 24-105 lens for the RF mount, so it looks like they are really trying to catch up in the mirrorless game.

Finally, the official announcement for the Canon 1DX Mark III is out!  You can view it on Canon Canada’s website here. This comes almost 4 years after the announcement of the 1DX Mark II (which was announced on February 1, 2016).   And since the teaser by Canon at the end of last year, I have been anxiously awaiting it.


Resolution & Processor

The Canon 1DX Mark III comes with 20.1 megapixels, which is the same number of megapixels as its predecessor.  Some people are a little disappointed that there have been no change in the number of megapixels, and while 24ish would have been nice, I am not overly disappointed that there is no change, I find 20 to be a nice sweet spot.


The camera comes with a DIGIC X image processor, and the autofocus system comes with a dedicated DIGIC 8 processor that will help to improve the autofocus speed and accuracy.   The image processor is advertised to have better ISO performance and dynamic range.  The ISO range has increased to a maximum of 102400, expandable up to 819200, but those are just numbers.  The question will be what the useable ISO for the camera will be, and whether it will be improved over the 1DX Mark II.



The biggest improvement in the camera is the advertised autofocus.  The 1DX Mark III comes with 191 total autofocus points, all of which are f/8, and there are 155 cross-type autofocus points.  With a dedicated DIGIC 8 processor, it is expected (and advertised) that autofocus will be better than the predecessor. This compares to to the 61 autofocus points (41 cross-type) of the 1DX Mark II.

In addition to the increased number of autofocus points, the camera also comes with advanced autofocus with head, face, and eye detection to help improve autofocus of subjects.  I will be curious to see how it works with wildlife subjects, or if it works at all.


The 1DX Mark III comes with an improved RBG sensor, going from 360,000 pixels in the 1DX Mark II to 400,000, this should help improve the AF performance and metering.



The 1DX Mark III is built for speed, with an increase in the frames per second, going from 14 to 16 (through the viewfinder), and from 16 to 20 (live view).  What is more impressive is that the camera has a buffer of approximately 1000 images, which is outstanding…and finally I will no longer be cringing while the Nikons are still going and my camera is buffered out.


Weight & Build & Other

Overall there is a slight weight savings over the predecessor of approximately 90 grams (with battery) with the 1DX Mark III weighing 1440 grams versus 1530 grams, but the overall dimensions of the camera remain unchanged.


The camera is equipped with dual CF Express slots.  FINALLY, Canon has produced a camera with two slots, which both take the same memory card.  However, I am a little disappointed that I invested in CFast cards and read for the 1DX Mark II that cannot be used with the 1DX Mark III.


The battery will be the same that is used for the 1DX Mark II, so at least anyone running both cameras will not need two different chargers and batteries.


As for video, I am not going to dive into the details, as video is just something I do for fun (and mostly with a GoPro or iPhone), but the 1DX Mark III does come with 5.5k raw video at 60 frames per second, as well as 4K at 60 frames per second.


The 1DX Mark III doesn’t come cheap, it is price at $8,999CAD  ($6,499 USD), so I really hope that the AF performance is as good as advertised, because the price tag is steep.


I am looking forward to getting my hands on one but who knows when that will be.  I am still debating what I will use as a second body, and whether I keep my 5D Mark IV, or my 1DX Mark II.
